SPECIFICATION forming part of Letters Patent No. 571,755, dated November 24, 1896. Application tiled June 27, 1896. Serial No. 597,168. (No model.)

To (LZ whom t may concern:

Be it known that l, JOSEPH M. DORAN,a citizen of the United States, residing at Ogden, in the county of lVeber and State of Uta-l1, have invented certain new and useful Iniprovernents in Train-Pipes; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which forni a part of this specification.

Myinvention relates to a fluid-conduit coinposed of metallic piping-sections connected by a universal joint and adapted to take the place of the usual rubber pipe so largely used in train and other service where a iiexible conduit is necessary. It is well known that rubber pipe, when used in such capacity or wherever used for conducting hot air or hot water, soon rots and becomes worthless, thereby entailing constant expense and care to keep it in order.

The object of my invention is to overcome such diiiiculties.

To this end my invention consists in providin g a metallic universal pipe-j oint or pipe composed of a series of connected and uniif'ersally-movable sections constituting a continuous fluid-conduit of such a character as to be cheaply made, easy to operate and keep in order, and capable of long and severe wear.

In the accompanying drawings, Figure l `represents one side of my complete structure, in which parts are cut away and shown in dotted lines to better disclose the internal construction. Fig. 2 represents a top or plan Yiew of n1 y device, in which some of the parts are shown in section.

The reference-numeral l denotes one of a series of hollow T- shaped frames or joint members, each of which is formed, preferably, of a single casting. The cross-arm 2 of the casting Vis provided with a longitudinal passage 3, the ends of which extend through the inside wall 4 of the casting land communicate with an elbow 5 through the medium of what will be called, for convenience, a niple ti. This nipple coincides with the bore of the elbow, to which it is rigidly secured by arm 2 of the frame l.

screw-threads 20, and is made steam and water tight by a stuffing-box consisting of an externally-threaded nut 7, which screws into interna-l threads 2l in the T- frame. A recess S is provided for the reception of a packingrin g D. The inner end lO of the nut is turned down smooth in order to enter the recess in the operation of compressing `the packing when the nut is screwed in, and squared surfaces ll are made on the outer end of the nut for the application of a wrench. An internal annular recess l2 is bored in the end of the elbow and is given a size and depth tol easily receive the packing-nut when the latter is nnscrewed in the operation of attending to the renewal of the packing or of taking the structure apart. the nipple is turned down smooth in order to closely t the stuffing-nut, whereby a tight hinge-joint is made. On the opposite side of and in axial alinement with the nipple is an embossinent 13,internally threaded to receive a bolt 14, which passes through a iiat plate l5, forming two arms parallel with the cross- Thus the nipple and bolt constitute a pair of trunnions on which the elbow 5 rocks during the vibrations of the conduit. The plate l5 is rigidly fastened to the stein 1G of said casting by a pair of screw-bolts 17, and its opposite end is secured to a twin elbow 1S, which is attached to the opposite side of the cross-arm on the T- frame by a screw-bolt and nipple in precisely the saine way that the elbow before described is fastened, so that a description of one will sufiice for both. lt is apparent that this duplication of parts will greatly facilitate and cheapen the manufacture of the device in addition toinalring it much easier for repairs and attention. The left-hand elbow 1S is in turn connected to the hollow cross-arm of a duplicate T-shaped member, disposed to lie with the stein extending at right angles to the iirst member, by a duplicate thimble, bolt, and plate, and so on throughout, thereby constituting a chain conduit composed of universally-j ointed sections capa-ble of oscillation in all directions and performing the saine functions of a flexible train-pipe.

The terminals of the conduit can be provided with any suitable connections by which The outer surface of IOO a Light joint 051.11.13@ .made btween them and, nipple,YK whereby the two are made *to comthe tw@ VmovableY hoies tofvhich inhoynm m# 1x1-unicam, f1.'11d'a-stignu't embracing. the tacked.'
